Background

Fuzhuan tea is bought out in 1368 D.A. of Gong Yuan, adopts tea of Shannan, Sichuan and the like as raw materials, is manually built, and is called as a Jingyang brick because the raw materials are sent to Xianyang Jingyang to be built; it is called "Fu tea" because it is processed in hot days. The efficacy of the medicine is similar to that of glabrous greenbrier rhizome, and the Fuzhuan tea is called Fuzhuan tea or Fuzhuan tea in the American style. Various extracted components of the Fuzhuan tea, namely the golden flower, have the effects of remarkably reducing human body lipoid compounds, blood fat, blood pressure, blood sugar, cholesterol and the like. The Fuzhuan tea can promote and regulate metabolism, enhance the physique of a human body and delay aging after being drunk for a long time, and has effective pharmacological health care and pathological prevention effects on the human body. The special efficacy of the Fuzhuan tea is widely accepted by experts in the fields of tea science, medicine, microbiology and the like.

The traditional Fuzhuan tea making process generally comprises the following steps: adding water into raw tea, uniformly piling, steaming, pressing, shaping, growing flower and drying. The floating is a special process for manufacturing the Fuzhuan tea, and other teas do not have the unique process. The flower growing is realized by growing and propagating eurotium cristatum in the brick tea which is molded by encapsulation and forming spores, namely golden yellow particles 'golden flowers' which can be seen by naked eyes of people. In the traditional process, the production period of the Fuzhuan tea needs several months or even longer, the amount of the golden flower of the Fuzhuan tea is small, and the quality is difficult to guarantee.

The water containing the spore of the golden flower fungus has the concentration of 10⁶cfu/ml golden flower fungus spore.

The manufacturing process of the Fuzhuan tea further comprises a step of adding bacteria, wherein the bacteria are added after steaming and before pressing; the bacteria is added by adding tea containing eurotium cristatum into softened raw tea.

The using amount of the tea added with the bacteria is 0.1-1% of the weight of the raw tea.

The tea leaf containing golden flower fungus has a concentration of 10⁸cfu/g golden flower fungus spore.

The golden flower fungus is sequentially subjected to a tea water culture medium acclimatization stage and a tea culture medium acclimatization stage.

The tea water culture medium domestication stage is to utilize the tea water culture medium to carry out growth domestication on the golden flower fungus, and the golden flower fungus can grow well on the tea water culture medium without cane sugar by gradually reducing the content of cane sugar in the culture medium; the tea culture medium domestication stage is to utilize the tea culture medium to carry out growth domestication on the golden flower fungus after the tea culture medium domestication stage, and the golden flower fungus can grow well on the tea culture medium without cane sugar by gradually reducing the content of cane sugar in the culture medium.

The tea culture medium is; the formula of the tea water culture medium is 200g of raw tea, 1000ml of distilled water, 30g of agar and 0-2g of cane sugar; the formula of the tea culture medium is 8g of raw tea/flat plate and 0-5.0% of sucrose solution.

Adding water to make the final water content of tea leaf be 20% -25%;

uniformly piling the raw tea added with water for 5-12 hours to ensure that the tea fully absorbs moisture;

steaming is to steam the raw tea for 10 to 20 seconds by a steaming machine, wherein the steaming temperature is 100 ℃, so that the raw tea is softened, and the raw tea is convenient to press bricks and shape;

and (4) pressing, namely performing mould pressing on the softened raw tea by using a brick press to form a brick shape.

The shaping is to stack the pressed Fuzhuan tea blocks together and press the Fuzhuan tea blocks by a weight, so that the Fuzhuan tea is better shaped and is not easy to disperse, and the shaping time is 6-24 h;

the shaped Fuzhuan tea is put into a flower growing chamber, the flower growing temperature in the chamber is controlled to be 25-30 ℃, the humidity is controlled to be 50-80%, the flower growing time is 5-10 days, and the preferable time is 7-8 days;

and (3) after the flowering is finished, transferring the Fuzhuan tea to a drying room, controlling the temperature of the drying room to be 40-60 ℃, and drying for 3-5 days.

Aiming at the problems of long manufacturing period, few golden flowers, low quality and the like of the prior Fuzhuan tea, the inventor establishes a Fuzhuan tea manufacturing process on the basis of the traditional mode, and the raw tea is sequentially subjected to the steps of adding water, uniformly stacking, steaming, pressing, shaping, growing flowers and drying, wherein the water containing the golden flower fungus spores is used as the water; optionally adding bacteria before pressing after steaming; the bacteria is added by adding tea containing eurotium cristatum into softened raw tea.
